FLYING MACHINE.

Application filed February 5, 1928. Serial No. 86,325.

This invention comprehends the provision et a combined airplane and helicopter, wherein upper and lower pairs of win s are mounted for rotation in horlzontal panes,

fi' and capable of being quickly and conveniently adjusted as a unit to occupy the desired angle with relation to the body of the machine, while each wing is capable of tilting 'movements within certain limits to properly le position themselves with the change of air currents.

'The natureand advantages of the invention will he readily apparent when the following detailed description is read 1n conlt neetion with the accompanying drawings, the intention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this titl application, like numerals of reference indicate similar parts throughout the several views, and wherein:

Figure 1 is a side' elevation ofthe machine constituting the subject matter of the 1nvention.

ltigure 2 is a front elevation.

Figure 3 is a top plan view.

Figure 4 is a perspective Viewy of one of the upper wings.

Figure 5 is a similar view of one of the iower wings.

Figure 7 is a view showing how the wing structure is capable of assuming an angular position with relation to the vertical.

lligure 8 is a sectional view on line 8-8 oi' Figure 7.

Referring to the drawings in detail, 10 represents a wheeled frame or bod machine, the front wheels being ind1cated at 1l and mounted on an axle arranged in a housing 12. The rear wheel is indicated at te 13 and is mounted on the frame so that it can be easily turned together with the rudder 14 for the purpose of steering the machine under any and all circumstances. For this purpose I make use of asteering post 15 ae which has associated therewith a sprocket wheel 16 over which and a smaller sprocket wheel carried by the standard of the wheel 13 are trained chains 17 and 18, respectively,

the corresponding extremities of these chains being connected by rods or wire elements 19. it. pair of handle bars 20 is associated with 24, while the steering post 15, and in convenient reach of the operator when occupying the seat 21, so that the wheel 13 and rudder 14 can be easily turned for the purpose above stated.

Rising from the body of the machine are standards 22, and pivoted on these standards is a casing-like head 23 upon which the wing structures are supported. Journaled in this head and projecting above the latter is a shaft 24 to` which is keyed or otherwise suitably secured the hub 25 of the su porting 'bracket 26 for the upper pair ci) win s, while below the hub 25 is the hub 27 of die support 28 for the lower pair of wings, thus hub 27 being mounted for rotation upon the shaft 24. The wings of the upper pair are indicated at 29, while the wings of the lower pair are indicated at 30, and it will be noted upon inspection of Figures 4 and 5 that the wings 29 project horizontally from the shaft the wings 30 of the lower pair are dropped to a plane beneath the wings 29 by the rods 31 forming part of the supporting structure therefor. The wires for the wings in each instance are indicated at 32. These wings are mounted for rotation in horizontal planes, the wings of the upper pair being rotated in a direction opposite the direction of rotation of the wings of the lower pair. The wings are rotated by means of a I'notor 34 which is connected with the wings in a manner to be presently described.

Upon reference to Figure 8 it will be noted that theshaft 24 has keyed or otherwise suitably secured thereto a bevelled gear 35, which meshes with a similar gear 36 keyed upon a shaft 37 while also keyed upon this shaft is a sprocket wheel 38 over which is trained an endless chain 39. The motor operated shaft 4() has secured thereto a sprocket wheel over which is trained an endless chain 41, the chain also bein trained over a sprocket wheel carried by te driven shaft 42, while the chain 39 above referred to is also trained over a sprocket wheel carried by the same shaft 42. Consequently, when the motor is in operation, rotation of the shaft 42 operates the chain 39, the latter' in turn rotating the shaft 37 which imparts rotary motion to the shaft 24, thereby o rating the upper pair of wings29. The s aft 42 carries a gear 43 which meshes with a gear 44 carried by a shaft 45, and mounted on this shaft is a sprocket wheel over which is trained an endless chain 46. This chain 46 is also trained over a sprocket wheel 47 iixed upon a shaft 48 journaled in the head 23, and in axial alinement with the shaft 37, as clearly illustrated in Figure 8. This shaft'48 is provided with a beveled gear 49 which meshes with a. similar gear 50 keyed or otherwise suitably secured to the hub 27 Aot the lower wing supporting structure, so

that when the shaft 48 is rotated simultaneously with the rotation of the shaft 37, the hub 27 is operated to rotate the lower pair ot' wings.

As above stated, the head 23 is pivoted as at 51 upon the standards 22, so that the wing structure in its Ientirety can be tilted to any desired angular position with relation to the standards 22, as illustrated in Figure 7, depending upon the course to be pursued by the machine. To accomplish this, I provide a sprocket wheel 52 which is journaledon the shaft 37 and secured tb the head '23 m any suitable manner, preferably by fastening elements 53, as shown in Figure 8. Also carried by the shaft 42 is a hub 54 which is provided with a sprocket 55 over..which is trained a chain 56, the terminals of which are connected by rods 57 with the corresponding terminals of a chain 58 trained over the sprocket 52 above referred to. The

hub 54 is actuated by means of a lever 59,.

and it is manifest that when the hub is rotated in one or the other direction, the chains 56 and 58 are called into use to tilt the head 23, and the wing structures as a unit to position the latter in any desired angle with relation to the standards 22, as shown in Fi ure 7.

s shown in Figure 1, I make usev of a chain tightener in the nature of a bell crank lever 60, one end of which has associated therewith a wheel 61 cooperating with the adjacent chain to hold the latter taut, while the other end of this lever is connected with a coiled spring 62 for-maintaining the lever in an active position. It will also be noted upon inspection of this f1 re and Figure 2 that the shaft 45 is provlded with a brake wheel 63 against which a brake shoe 64 0perates to retard the rotation of the wings as the occasion may require. This shoe is carried by a foot treadle 65 pivoted on the standards as at 66 and connected with a spring 67 which normally holds the shoe spaced from said wheel and the treadle 65 elevated. The treadle, of course, is adapted to be depressed by the foot of the operator to move the shoe 64 into active position.

As hereinabove stated, each wlng is capable of tilting movements within certain 11mits, to properly adjust themselves under the influence of the air currents and the structure for this pur ose is clearly illustrated in Figures 4, 5 an 6. Each wing is pivoted as at 68 upon spaced u rights 69, the latter being stationary and ways maintained in parallelism with the shaft 24, while each wing is connected with one ofv the standards by means of a spring 70, which under normal conditions maintains the wing in a true horizontal position. lVhen iniiuencedhy the air currents, should the latter be strong enou h to overcome the tension of the spring 70, t e i upper and lower pairs of wings, the machine can be used in the capacity of a helicopter, and that when the machine has been ele vated to the desired altitude, the wings can be tilted'as a unit with relation to the body of the machine as the occasion may require, and the wings themselves tilted with relation to each other by air currents as described.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily ap arent, I desire to have it understood that vdo not limit myself to what is herein shown and described, and that such changes may be made when desired as fall within the scope of what is claimed. i Having thus described the invention, what 1s claimed as new, is
